OS X Yosemite: Green Dot is now Full Screen

Take the red, yellow, and green â€œstoplightsâ€ in the corner of every app window. Not only have we streamlined their look, but weâ€™ve also updated their functions. Close, minimize, and maximize are now close, minimize, and full screen, eliminating the extra full-screen control and consolidating the window controls in one place.

I hope this is not like Full Screen mode in Chrome, but more like Presentation Mode with all the chrome hidden.
